“…Even under cultural conditions, several fish can undergo starving periods during stressful situations, changes in water quality, or disease outbreaks (Barcellos et al 2010 ; Sridee and Boonanuntanasarn 2012 ; Najafi et al 2015 ; Yang et al 2019 ). Skeletal muscle represents 40–60% of the total body mass in most studied fish (Weatherley and Gill 1985 ) and principally represents white muscle, the edible part of the fish (Zhang et al 1996 ; Sänger and Stoiber 2001 ). Fasting and refeeding affect the muscle, one of the most critical tissues for aquaculture.…”

The current study investigated how different fasting and refeeding regimes would impact Nile tilapia growth performance, histopathological examination, and gene expression of myostatin, myogenin, GH, IGF-1, and NPYa. Nile tilapia fish (n = 120) were randomly allocated into four groups, including the control group fed on a basal diet for 6 weeks (F6), group A starved for 1 week and then refed for 5 weeks (S1F5), group B starved for 2 weeks and then refed for 4 weeks (S2F4), while group C starved for 4 weeks and then refed for 2 weeks (S4F2). Fasting provoked a decrease in body weight coincided with more extended starvation periods. Also, it induced muscle and liver histological alterations; the severity was correlated with the length of fasting periods. Gene expression levels of GH, MSTN, MYOG, and NPYa were significantly increased, while IGF1 was markedly depressed in fasted fish compared to the control group. Interestingly, refeeding after well-planned short fasting period (S1F5) modulated the histopathological alterations. To some extent, these changes were restored after refeeding. Restored IGF-I and opposing fasting expression profiles of the genes mentioned above thus recovered weights almost like the control group and achieved satisfactory growth compensation. Conversely, refeeding following more extended fasting periods failed to restore body weight. In conclusion, refeeding after fasting can induce a compensatory response. Still, the restoration capacity is dependent on the length of fasting and refeeding periods through exhibiting differential morphological structure and expressions pattern for muscle and growth-related genes.

“…Similarly, the potential for red muscle endothermy in L. imperialis was explored by quantifying the longitudinal and transverse distributions of the red muscle and comparing them to those of species known to be ectothermic or regionally endothermic with respect to their red muscle. Literature values were used in quantitative comparison to L. imperialis with respect to the (1) longitudinal distribution of the red muscle as a proportion of total body cross‐sectional area (Dickson et al ., 2000; Graham et al ., 1983; He, 1986; Johnston et al ., 1988; Johnston & Camm, 1987; Malik et al ., 2020; Zhang et al ., 1996), (2) relative red muscle area compared to that at 50% fork length (Bernal et al ., 2003, 2010; Bernvi, 2016; Ellerby et al ., 2000; He, 1986; Sepulveda et al ., 2005), (3) relative distance between the vertebral column and red muscle compared to that at 50% fork length (Perry et al ., 2007), (4) relative distance between the red muscle and body perimeter compared to total body width at 45%–50% fork length (Dickson et al ., 2000; Perry et al ., 2007; Stoehr et al ., 2020) and (5) normalized perimeter index (perimeter of a circle divided by that of the focal shape of equal area, 0 < x ≤1) of the red muscle cross‐sectional shape at 45%–50% fork length (Bernvi, 2016; Dickson et al ., 2000; Malik et al ., 2020; Perry et al ., 2007; Sepulveda et al ., 2005; Stoehr et al ., 2020). Furthermore, generalized additive mixed models (GAMMs) were used to predict across‐endotherm and across‐ectotherm estimates of the longitudinal distribution of red muscle as a proportion of total body cross‐sectional area and relative red muscle area compared to that at 50% fork length (accounting for shape constraint in the latter metric); these GAMMs predicted red muscle metrics as a function of fork length with a global, across‐species smoother and a random effect for individual species ( sensu Pedersen et al ., 2019).…”

Ectothermy and endothermy in extant fishes are defined by distinct integrated suites of characters. Although only ⁓0.1% of fishes are known to have endothermic capacity, recent discoveries suggest that there may still be uncommon pelagic fish species with yet to be discovered endothermic traits. Among the most rarely encountered marine fishes, the louvar Luvarus imperialis is a remarkable example of adaptive evolution as the only extant pelagic species in the order Acanthuriformes (including surgeonfishes, tangs, unicornfishes and Moorish idol). Magnetic resonance imaging and gross necropsy did not yield evidence of cranial or visceral endothermy but revealed a central‐posterior distribution of myotomal red muscle that is a mixture of the character states typifying ectotherms (lateral‐posterior) and red muscle endotherms (central‐anterior). Dissection of a specimen confirmed, and an osteological proxy supported, that L. imperialis has not evolved the vascular rete that is vital to retaining heat in the red muscle. The combination of presumably relying on caudal propulsion while exhibiting internal red muscle without associated retia is unique to L. imperialis among all extant fishes, raising the macroevolutionary question of whether this species – in geologic timescales – will remain an ectotherm or evolve red muscle endothermy.

“…There are three main classifications of muscle fiber types in fish: white, red and pink muscle fibers (Figure 1) [4]. White muscle runs the length of the fish, composes approximately 70% or more of the myotome of most fish and is typically the largest of the fibers, ranging from 50 to 100 µm [5][6][7]. Similar to mammals, white muscle in fish has low levels of myoglobin, vascularization and mitochondria content [8].…”

Typically, mammalian and avian models have been used to examine the effects of ammonia on skeletal muscle. Hyperammonemia causes sarcopenia or muscle wasting, in mammals and has been linked to sarcopenia in liver disease patients. Avian models of skeletal muscle have responded positively to hyperammonemia, differing from the mammalian response. Fish skeletal muscle has not been examined as extensively as mammalian and avian muscle. Fish skeletal muscle shares similarities with avian and mammalian muscle but has notable differences in growth, fiber distribution, and response to the environment. The wide array of body sizes and locomotion needs of fish also leads to greater diversity in muscle fiber distribution and growth between different fish species. The response of fish muscle to high levels of ammonia is important for aquaculture and quality food production but has not been extensively studied to date. Understanding the differences between fish, mammalian and avian species’ myogenic response to hyperammonemia could lead to new therapies for muscle wasting due to a greater understanding of the mechanisms behind skeletal muscle regulation and how ammonia effects these mechanisms. This paper provides an overview of fish skeletal muscle and ammonia excretion and toxicity in fish, as well as a comparison to avian and mammalian species.
